Hello everyone,

This is my first post in the forum and I am happy to be a part if the Briskoda community.

I own a Superb 2.0Tsi 190hp with engine DKZA (GPF) that have 5000km on the clock and the engine was filed from the factory with the 0w-20 50800 oil specification.

 

I just want to share something that it shocked me when I made my first oil change on my new Skoda superb facelift, the oil looked like it was driven 15000km! I remember that when I made the first oil change (5000km) on my last superb 1.8Tsi 2018 the oil was much much cleaner.

I suspect that the addition of GPF is the prime source of this problem, I wonder how the oil will look like after 30000km?!
I recommended to anyone that have GPF in his/her car to stay away from the QI6 flexible service.
I attach some pictures of the oil color.

Could you please explain why you think the GPF might be affecting oil degradation rate? It's early in the day, but I'm struggling to imagine a link.

The quality of the oil at the same mileage used to be far better on my Superb 3 EA888 prefacelift without GPF, I believe the major changes they made on the latest generation EA888 is to add a GPF and change to Budack combustion cycle, that's why I suspect the particulate filter. 

I suppose the engine could be mapped for a less efficient, cooler burn in order to lower NOx output, knowing that the extra soot produced won't make it past the GPF. Seems like a horrible compromise though.

That does look quite dirty. I just had mine 2019 MY (220 hp) serviced at about 5000 km, and the oil was nowhere near that dark. More of a slightly dark golden color.

Oil in diesels always looks very dirty, even a day after new oil was put in.

 

What is wrong with taking the sump plug out and getting rid of all the sludge out of the bottom!

This isn't a diesel.

Oil colour does not reflect it's quality or its ability to lubricate though.

Agree. Only way to find out more is oil analysis. 

 

I do love the budack cycle though. Hope it is as efficient as it should be. 

Does the 220bhp engine have a GPF? I've never heard of it.

I do about 20k miles per year, diesel was much cheaper to run but dirty and horrid. The reason I switched from diesel to petrol after years was because of issues with DPFs....

Does that oil pump well? Looks very neat. If so do you have a link for it?

Maybe the additive package in that oil is so brilliant it has managed to keep all the dirt from your engine is suspense therefore actually doing a better job of getting the dirt out and not leaving it in your engine.

I know that the color doesn't mean that the oil is bad, but I was just comparing the oil color between the EA888 3b and EA888 gen3.

I thought about that too.

When I looked at some specialized engine oil forums I didn't find much info about the new 508 00. I will see if I can analyse the oil, I think there is a company in Germany that can do it for a reasonable price.
But still, I can't swallow that that color is normal at this early stage.

Yes it does pump well on the EA888 because of the flat oil sump but don't buy it if you have a diesel or a EA211 because it won't suck all the oil. I bought it from a UK website, I don't know if I am allowed to post links but you can search for Sealey tp69 I believe i bought it for GBP 53.

Good luck.

No, the 220 have no GPF, the 190 and 272 have it.

I always thought first fill oil contained extra additives to aid running in, particularly camshafts and was not to be drained early. 

Not sure why anyone would buy an eco version of the 2.0TSi petrol engine unless you get some massive tax break for being an eco warrior. Like yours mine has a GPF but unlike your engine mine loves to rev and produces 360bhp on 99 octane petrol. Over 3,500 miles it is averaging 38mpg with a best so far commute of 44.4mpg in Eco mode with the climate control always on. Curious to know what the slow version of this engine is giving you for comparison. Mine does 0-160kph in 10.46 seconds on a drag strip of course.Done 8,400 miles since it left the factory over a year ago on the same Long Life oil and on variable servicing so computer says it will be due new oil at about 24,000km (15,000 miles).

The broken record repeating the same old lines everybody is fed up of hearing again and again and again and .....

Iirc, many years ago, some manufacturer's first fill oil was mineral, not synthetic to help bed in rings etc. and an early change to synthetic could slow the running in or even stop it such that oil consumption ends up on the high side.

 

But I think todays materials, production methods and control, render it unnecessary and Skoda use synthetic oil to 508/509 0w-20 as first fill. Many including myself have had this "confirmed" by Skoda customer services.

 

Have read somewhere that early or too frequent changes can under certain circumstances lead to issues but personally I doubt it.

 

@joeyx Dirty oil may be due to the budack cycle or increased use of in head egr using extended valve overlap timing. At least it shows the detergent in the oil is doing its job in cleaning the engine and holding the carbon in suspension.

The cynic in me makes me think that one of the main reasons Skoda use the extremely low viscosity VW508.00 0W20 oil in the factory is to help them to meet the ever stringent emissions tests, including helping VAG to overcome the painful delays in achieving WLTP for a lot of their engine configurations a couple of years ago.

 

The fact that my dealer replaced the factory 0W20 with 5W30 (VW504.00/507.00) at its first service only fed my suspicion.

 

I could be wrong of course, but I'm happier knowing my 1.4 TSI is now running 5W30.

Its simply to reduce the official test CO2 figures as low as possible. Look at the financial penalties set by the EU for exceeding fleet average CO2 targets. Every gm/km saved equates to millions of euros avoided in penalties for VAG.

 

Once the car has left the factory, they don't care what oil you use at service (only that it meets their one of their approved specs to stop it breaking during the warranty period).

Would that account for the rise in fuel consumption after the first service? Would it do any harm to keep the engine on 0W20?

Yes, you probably have 5w30 in now, or if unfortunate enough to have a dealer like mine, 5w40

 

It probably wouldn't harm to keep using 0w20, not enough history to draw firm conclusions though.

 

If you want to see clean oil then you need an engine with a centrifugal oil filter like the old school Fiats that used a large diameter flanged galleried crankshaft pulley that you were supposed to split when doing an oil change to scrape out the compacted crud which looked just like a rubber moulding.

 

The oil came out as clean as it went in.

 

I remember an OCD garage owners son that would use Duckhams 20/50 oil in his car and change it as soon as it no longer looked green on the dipstick.
